Question

find the mean deviation about the mean for data 3, 6, 10, 4, 9, 10.

Answer 1

MEAN - sum of observations/no. of observations.
SO,
3+6+10+4+9+10 = 42
no. of observations = 6
SO,
42/6 = 7
SO, answer = 7

Answer 2

Heya friend !

ANSWER :-

We know ,
Mean of observations =
$\frac{sum \: of \: observations}{no \: of \: observations}$
So ,
$= \frac{3 + 6 + 10 + 4 + 9 + 10}{6}$
$= \frac{42}{6}$
$= 7$
Therefore , Mean of observations = 7
